Deformed Harish-Chandra homomorphism for the cyclic quiver
arXiv:math/0504395
Abstract
In the case of cyclic quiver we prove that the deformed Harish-Chandra map whose existence was conjectured by Etingof and Ginzburg is well defined. As an application we prove Kirillov-type formula for the cyclotomic Bessel function.
